Definitions

  • the invention relates to a machine for manufacturing a material web, in particular a paper or Cardboard web according to the preamble of claim 1, and a method for producing a material web according to the preamble of claim 5.
  • Machines of the type mentioned here are known (DE 33 22 996 C2). They have a dryer section with at least one double-row dryer group on. This distinguishes two-tier dryer groups from that they have two rows of heatable Have drying cylinders, each one also felt referred to as a dryer fabric is assigned, the drying cylinder together with the material web assigned to a row and the drying cylinders Deflection rollers revolves around in a meandering shape the web of material against the surface of the drying cylinder invests. The material web rotates alternately the drying cylinders of the two rows of double row dryer group, so that alternately the Top and bottom of the material web with the drying cylinders comes into contact.
  • the well-known machine has a drive that drives the drying cylinder rotated and one revolution of the Felt the dryer section.
  • the material web becomes the following Threaded into the machine: First the material web is only until the end of a so-called Press section or up to the beginning of the drying section guided and arrives during a start-up phase in an area below the machine in a reject dissolver. The material web is running practically at full working speed. First the track becomes a relatively narrow one Edge strips separated, which as a ribbon or threading strip referred to as. This will initially passed through the dryer section, the one and can include two-tier dryer groups. It it is known that the insertion of the threading strip is problematic. Among other things also ropes are used to help, but the threading process not with the necessary security guarantee, on the other hand also a danger mean for operators.
  • the machine is characterized by that the drive is designed so that the speed of rotation of the two rows of drying cylinders within the two-tier dryer group can be controlled independently of one another. It is with it possible to hand over the ribbon respectively To influence the threading strip so that the threading process can be carried out with a high degree of certainty.
  • the machine is also characterized by that the drive is designed so that during the transfer of the threading strip within a double row Drying group the row of drying cylinders Threading strip passes, at least temporarily rotates faster. It has been found that thereby a safe takeover of the threading strip can be guaranteed.
  • An embodiment of the Machine which is characterized in that the speed of rotation the threading strip taking over the first row of drying cylinders is approx. 1 ⁇ greater than the speed of rotation the second row of drying cylinders, the takes over the threading strip from the first row.
  • a method is also used to solve this task proposed for the production of a material web, comprising the features mentioned in claim 5. It is characterized in that the two rows of drying cylinders in a two-row dryer group with mutually independent speeds of rotation are driven. This can ensure that the threading strip is secure is taken over.
  • the schematic shows a section of one Double-row dryer group 1, which is part of a dryer section a papermaking machine 3.
  • Drying group 1 has a first row of Drying cylinders 5, 7 and 9, whose centers lie on an imaginary level E1. Relocated to the drying cylinders 5, 7 and 9 are the Drying cylinders 11, 13 and 15 of a second row arranged by drying cylinders, their centers lie in an imaginary plane E2. The two levels are at a distance from each other and are here arranged parallel to each other. However, it is conceivable, other arrangements of the drying cylinder provided.
  • the first row of drying cylinders 5, 7 and 9 are deflection rollers 17, 19, 21 and 23 assigned to the the deflection of one also as a dry felt or sieve designated conveyor belt 25 serve that together with the material web 27 around the drying cylinder 5, 7 and 9 is led around.
  • the material web 27 is guided so that it is on the surface of the drying cylinder rests and from the conveyor belt 25 or 37 against the Surface is pressed.
  • the web of material runs alternately around the drying cylinders of the top Row and the bottom row, so that alternately the Bottom or top of the material web is dried.
  • the material web 27 on the first drying cylinder 5 applied to the top row of drying cylinders and arrives from the first drying cylinder 5 top row on the first drying cylinder 11 of the lower row of the two-tier dryer group 1.
  • Dryer group 1 is equipped with a drive the one here the first drying cylinder 5 the upper row associated motor 39 and a assigned to the first drying cylinder 11 of the lower row Motor 41 includes. It is possible to have several the drying cylinder of a row has its own Assign engine. However, it is also conceivable that the torque introduced in a drying cylinder via the conveyor belt 25 or 37 transferred to the other drying cylinders in a row becomes. Finally, it is also possible Design the drive so that the conveyor belts 25 and 37 are driven by separate motors and set the drying cylinders in rotation.
  • the drive of dryer group 1 is designed so that the speed of rotation the drying cylinder 5, 7 and 9 of the first row of the Drying group 1 can be set independently of the Rotational speed of the drying cylinders 11, 13 and 15 of the second row of drying group 1. Es is possible, the rotation speeds of the two rows of drying cylinders so one on top of the other vote that a ropeless transfer of a so-called ribbon or threading strip is easily possible.
  • a difference in the rotational speed is preferred from approx. 0.3 ⁇ to approx. 1.8 ⁇ .
  • there has been a difference in the rotational speeds from 0.6 ⁇ to 1.4 ⁇ proven.
  • a speed of rotation is very particularly preferred of approx. 1 ⁇ .
  • the procedure also results from the above for the production of a material web, in particular a paper or cardboard web that can be used for everything characterized in that the two rows of Drying cylinders 5, 7 and 9 and 11, 13 respectively and 15 of drying group 1 with mutually independent, preferably with different speeds of rotation are driven. It has turned out to be particularly advantageous, at least a drying cylinder in a row an engine assign and ensure that the series the drying cylinder has a higher rotational speed that the material web at the beginning the drying group and this to the second row of drying cylinders passes.
  • the second row has its own engine.
  • the different speeds of rotation can be realized particularly easily if at least one drying cylinder in a row is powered by its own engine.
  • Another essential aspect is that a mechanical Coupling of the two motors 39 and 41 is not necessary, so the rotation speeds are particularly easy to adjust. At the same time, the noise development is without one mechanical coupling particularly low.
